STAMP-AFFIXING MACHINE.

Specification Of Letters Patent. Patented Feb. 14, 1922 Application filed August 19, 1920. Serial No. 404,646.

To @ZZ who/m t may concern Be it known that I, HARRY J. BURR, a citizen of the United States, and resident of New Hartford, in the county of Gneida and State of New York, have invented a new and useful Improvement in Stamp- Atiixing Machines, of which the following is a specification. A

This invention consists in a stamp aiiixing machine in which the leading stamp of a` ribbon is folded back, moistened, separated and affixed as the machine is operated.

rlhe Object of this invention is to provide certain improvements in the construction, form, arrangement and operation of the several parts whereby the structure is materially simplified and the accuracy of opera` tion is ensured.

filhis invention is more particularly directed to improvements of the machine disclosed in United States Letters Patent No. 1239621, dated September 11, 1917, and in my application filed May 17, 1918, Serial No.A 235165. l

A practical embodiment of my invention is represented in the accompanying drawk ings, in which,

Fig. 1 represents a perspective view of the machine.

F ig. 2 represents a front view with the front door removed'.

Fig. 3 represents a section taken in the plane of the line IHHI of Fig. 2.

Figs. 5, 6, 7 and 8 represent front views with the door removed, the parts being shown in the positions which they assume as the handle is depressed to different positions.

Figs. 9 and 10 represent front views with the door and certain other parts removed to iilustrate the position of the frame plate j ust before and just after it has been released froin the handle at the limit of its depressed movement.

Fig. 11 represents a section on an .enlai-ged scale, taken in the plane of the line Xl-XI of Fig. 6.

l? ig. 1,2 represents a perspective view of the drum and the parts carried thereby.

Fig. 13 represents a perspective view of the drum plate and the parts carried thereby.

The casing 1 is provided with a front door 2, which door is preferably provided with a transparent window whereby the action of the parts within the easing may be observed. This casing is provided with an Opening 3 through its bottom. A frame plate 1 has a limited vertical sliding movement between retaining guides 5 and 6 fixed to the back wall of the casing. A stud shaft 7 extends forwardly from the frame plate 4f and on this shaft there is loosely mounted the sleeve 8 of a rocking cam lever 9 which coacts with an abutment 10 uprising from the bottom of the casing 1, for controlling the relative vertical movement of the frame plate with respect to the casing as will hereinafter appear. i

The operating handle 11 has its shank 12 slidable through the top of the casing 1, the lower end of which shank is secured to the forwardly turned upper end 13 of a slide 14 located within the casing between the back and the frame plate f1, in the present instance, in a shallow groove 15 formed in the back of the casing. This slide 14 is provided with a forwardly extended stud 16 which travels in a vertical groove 17 in the frame plate 1. The forwardly turned upper end 13 of this slide 14 travels in a vertical groove 18 in the upper end of the frame plate. v

The stamp drum comprises the back wall 19 and the cylindrical side Vwall 20, which drum has a hub 21 which is loosely mounted on the sleeve 8. The side wall 20 of the drum is divided to form a slot 22 through which the stamp ribbon passes. Adjacent to the slot 22 the drum is provided with a` presser foot 23.

A. drumV plate 24 is loosely mounted on the hub 21 of the drum in close proximity to the' back wall 19 of the drum, which plate is provided with two forwardly extended arms 25, 2G, over and under which the stamp ribbon passes on its way to the exterior of the drum. A curved spring arm 27 is secured at one end to the under face of the forwardly extended 25 of the drum plate, the free end of the arm extending around and in close vproximity to the side wall, 29 of the drum, across the slot` 22 and through an inwardly turned rib 28 of the side wall. This spring 27 presses the stamp ribbon against the forwardly projecting arm 26 of the Idrum plate24.

The back wall 19 of the drum is provided with an elongated slot 29 into which the stud 16 on the slide 14 projects.

A stamp severing knife 80 is located in front` of and normally against the front end i of the presser foot 23, which knife forms the lateral extension 4of a lever 31, pivoted at 32 to the back wall 19 of the drum. This lever is provided with an off-set portion 33 which has a limited movement in ai slot 34 in the back wall of the drum.

it helical spring 35 surrounds the hub V21 of the drum7 one end of which spring passes through a slot 36 in the drum plate 24 and a slot 37 in theback wall of the drum into engagement with `the knife lever 31. The other end ojthis helical spring is seated in. a kerf 38 in the end of the sleeve 8, and a wider kerf 39 in the end of the stud shaft 7, thereby permitting` the sleeve 8 and its cam r lever 9 a limited rocking movement under spring tension. The swinging' movement of the rocking cam lever 9 against the tension of the helical spring 35 is obtained by the engagement of a stud 109 on the lever with a cam surface 114 at fthe lower` end of the slide 14. which cam surface leads to a slot 214 for receiving `the said stud 109.

i4 folding lever 40 for folding over the leadingstamp of t-he ribbon on Ithe return movement of the drum is pivoted at 41 to the back wall of the drum, the outer end 42 of which lever is turned laterally across the drinn in `front` of the knife 30. The inner arm 4?) of this lever is provided with a cam surface 44 arranged to engage a. stud 45v which projects forwardly from the frame plate 4.1said cam surface 44 terminating in a hook 46 for swinging the folding lever as the drum is oscillated.

This stud projects forwardly through an elongated concentric slot 47 in the back wall into an elongated concentric slot 48`in the drum plate 24. The drinn plate 24 is provided with a latchlever 49 pivoted at 50, which latch lever is fitted to travel back and forth in the slot 47- of the drinn. This latch lever is provided with a nose 51 on its inner edge which is adapted to be brought into and out of the notch in the inner wall of the slot 47.

The width of the slot 48 is the same as the diameter of the stud 45, but the slot 47 is considerably wider so that when the latch lever 49 locks the drum plate 24 to the drnm bythe entrance of the nose 51 into the notch the stnd 45 may pass between the outer edge of the latch lever 49 and the outer edge of the slot 47. Then the nose 51 of the lever 49 is forced ont of its notch 52 it will hold the stud 45 at one end of the slot 48.

A stamp moistening reservoir 53 is carried by the lower end of a lever 54, pivoted at 55 to the back of the casing, a spring 56 serving to normally hold the reservoir at the limit of its outward movement away from the drum.

This moistening lever is operated from the handle 11 as follows zcam dog 57 is mounted to have both lateral and swinging movements on the stud 58 which projects upwardly from the drum plate 4. A spring 59 serves to yieldingly hold the dog at the limit of its lateral movement against the drum plate 4. The bodyV of the dog is bent to form a cam 60 anda double cam surface 61 is formed along the inner edge of the dog. The forwardly turned upper end 13 of the handle slide 14 is provided'with a recessv 62 through which the cam surface 61 of the dog passes on the upward movement of the handle, the dog. being swung backwardly to swing the moistening reservoir inwardly during the downward movement of the handle by the engagement of the cam surfacel 61 of thedog with the adjacent edge of `the forwardly turned upper end 13 of the plate 14 at the side of the recess 62.

The reservoir 58 is provided with a stamp moistening device suchas a wick 63 and it is also provided with a suitable water inlet 64 which passes through an elongated slot 65 in the back ofthe casing.

The means for ensuring the full downward or backward movement of the handle to complete the cycle of operations of the machine when once started, is follows A double pawl 66 is pivoted at 67 to the hack of the frame plate'4, which pawl is located within a vertical slot 68 in the handle slide 14 in position to engage the teeth of a rack 69 along one side of the slot. A spring 70 serves to hold the double pawl yieldingly` in engagement with the rack.

The top wall of the slot 68 has a cam sur-- face 71 arranged to engage the pawl to throw it over to one position when the slide is depressed to the limit of its movement and the bottom wall of the said slot has a cam surface 72 arranged to engage the pawl and throw it over to itsother position when the slide is raised to the limit of its upward movement, the spring 70 acting to yieldingly hold the paw] in either of its operative positions.

rlhe stamp ribbon is clamped to and released from the drum at different'points in the movement of the drum by the following means j j Y A clamping leverf73 ismonnted on a pin '74 projecting forwardly from the back vwall. of the drum. This lever is providedwith a nose 75 which travelsalong the periphery of the drum plate 24 into and out of a notch-76 in said periphery. A sjiring '77 tends to swing the nose 75 of the clamping lever inwardly and the ribbon clamping surface of the said lever outwardly. lt will be understood that the roll of stamps 78 is mounted on the movable core 797 which surrounds the spring The ribbon leading from this roll passes between the arm 25 and the side wall 20 of the drum. From thence it leads between the arm 26 and spring 27. From thence it leads between the clamping lever 73 and the side wall of the drum. AAlfter it leaves this point it passes outwardly through the slot 22 in the side wall of the drum7 underneath the knife 30 and over the laterally turned arm l2 of the folding lever.

rlhe operation ofthe machine is as follows 2- Let it be supposed that the parts are in their normal position, shown in Fig. 2, with the .leading stamp of the ribbon folded back over the knife by the outward movement of the folding lever. The machine is placed upon the article to which the stamp is to be afhxed and the handle 22 is depressed to the limit of its downward movement. During this downward movement the following conditions obtain:

is the handle is started on its downward movement7 the drum will be rocked' forwardly by the engagement of the slide stud i6 with the wall of the slot 29 in the back wall of the drum to move the drum against the tension of the helical spring 35. As the drum rocks in this forward direction, the cam surface 1li-l; of the folding' lever will l e engaged by the stud a5, carried by the frame slide 4, for swinging the laterally turned outer end 4-2 of this lever inwardly snugly against the side wall of the drum in front of the stamp severing knife 30. It will be noted that the drum plate 24. is held against rotary movement by the raising of the latch lever 49 to partly close the slot 48. lt will also be noted that the stamp ribbon clamping lever 73 is held out of its clamping engagement with the ribbon. The positions which the parts assume up to this time are indicated in Fig. 5. The further downward movement of the handle and its slide will rock the drum still further in its forward direction, taking the stamp ribbon with it and causing the back of the folded over leading stamp to be wiped across the wick G3 of the moistening devi.ce the moistening reservoir having been swung inwardly by the outward' movement of the cam dog 57, due to the engagement of its cam surface Gl with the forwardly extended upper end 13 of the lhandle slide. ln the meantime the nose of the clamping lever 73 has been brought opposite to the notch 7G in the drum plate, thus bringing the clamping surface of the said lever into position to clamp the stamp ribbon against thev side wall of the drum. ln the meantime the turned over stamp located between the arti-.

cle to which the stamp is to be affixed and the presser foot 23. ln this movement. the drum and drum plate are moved together as the latch lever a9 has been forced inwardly by the stud Ll5 to bring the nose l of the latch lever into the notch thus permitting thel stud l5 to travel along both the slots 47 and l-o in the drum and drum plate respectively. In the meantime the moistening device has been permitted to be swung outwardly out of Athe way.. 1With the parts in this position a portion of the elongated slot 29 is brought into a substantially vertical positionwith the stud lGabor-.t to enter the vertical portion of the slot.

The further slight downward movement of the handle and its slide will cause the cam lever stud 109 to be engaged by the slide cam surface 114 to swing thefcam lever 9 against the tension of the helical spring 35, out of its locking engagement with the abutment l0 on the bottom of the casing and thus permit the bodily downward movement of the drum and drum plate together with the parts carried thereby, with respect to the casing, whereby the moistening stamp is pressed rmly against the article to which it is to be aliixed. It will benoted that this slight downward movement has brought the slide stud 16 into engagement with the knife lever 31 and has swung the knife leverl against the tension of the helical spring 35 to move the knife 30 a short distance away from the presser foot 23 suliiciently to sever the affixed stamp from the ribbon. This final downward movement of the handle and its slide will also cause the double pawl 6G which has been locking the handle slide against upward movement, to be engaged by the cam surface 71 to throw the pawl over into the position to release the slide to permit the helical spring 35 to return the parts to their normal position. The positions of the parts at the limit of the downward movement of the handle are shown in Fig. 8.

As the downward pressure on the handle is removed, the irst operation will be the slight upward movement of the handle, the frame plate and the drum as well as the return of the knife 30 to its position against the front end of the presser foot 23. The cam lever 9 is also permitted to be' swung back into its locking position with the abutment l() under the tension of the helical spring 35. The further upward movement of the handle will permit the reverse rocking movement of the drum, the stamp ribbon being moved with the drum by the clamping lever T3 until the stud l5 reaches the front. end of the slot 48 when the reverse rocking movement of the drum plate is stopped. The further reverse movement of the drum will swing the nose of the clamping lever out of its notch '76 in the drum plate to release the stamp ribbon, and it will also swing the nose 5l of the latch lever 49 out of its notch 52 in the drum to lock the Ystud 45 to the drum plate. This reverse Inovement of the drum with the stamp ribbon released will cause the next succeeding stamp of the ribbon to be exposed beyond the presser foot and knife with a slightoverfeed. As the drum approaches the limit of its reverse rocking movement, the laterally turned upper end 42 of the folding lever will be swung upwardlyl bythe engagement of the stud 45 with the hooked end of the cam surface Liet of the said lever, thus folding the exposed stamp back over the knife into the position shown in Fig. 2. i

This slight over-feed ofthe stamp ribbon as the parts return to their normalpositions ensures the accurate folding over of the stamp along its separation line andthe proper engagement of the knife 30 in the apex of the folded over portion in the next succeeding operation of the machine.

During the return movement of theparts as above described, the cam dog 57 which controls the movement of thestamp mois tening device will, because of its shape -and laterally yielding movement ride through the recess 62 in the forwardly turned upper end 13 of the slide without rocking the dog and swinging the moistening device.

It is to be understood :that during the first part of the downward movement of the handle, the drum will move forwardly `along the ribbon until the `knife 30 enters the apex of the fold betweenthe ribbon and folded over stamp, when the ribbon willY be moved thereafter with the drum by the knife until clamped by the clamping lever 73 as hereinbefore described.

It will also be observed that as the handle and slide reach the limit of theirupward movement, the cam surface 72 of the slot 68 in the slide 14 will engage the double pawl 66 (which has been locking the slide against downward movement until it has completed its upward movement), to throw the cam over to its original position to lock the handle against upward movement once it has been started on its downward movement. This ensures the complete movement of the parts in either direction.

vWhile this machine is described as a stamp afixing machine, it is obvious that it may be used for aiiixinggummed labels of any character in ribbonform.
